Takua Pa to Koh Phi Phi: Road Trip Guide

Route 4 (Phet Kasem Road) cuts through the southern Thai isthmus, linking the sleepy mainland town of Takua Pa to the pier at Tha Lane or Ban Tha Din Daeng, where ferries leave for Koh Phi Phi. The road passes through Khao Lak and Phang Nga, crossing the Sarasin Bridge before reaching the mainland port. Most travelers use this route to access Ao Nang or Krabi Town for direct ferries to Phi Phi, so the drive itself often feels like a prelude to the Andaman crossing. This guide covers the essential details for a smooth journey.

The road quality varies: from well-paved in Khao Lak to narrower, two-lane stretches through Phang Nga. During the rainy season (May-October), some sections may be flooded or have reduced traction, especially near mountain passes. Always check conditions before departing. For families, the Khao Lak National Park’s nature trails and the Tsunami Memorial Museum in Ban Nam Khem educate and engage older children. The journey is manageable for kids if you schedule breaks every 90 minutes.

Pet-friendly framework: Many hotels in Khao Lak and Phang Nga accept pets, but ferries to Koh Phi Phi have limited pet allowances—contact Andaman Wave Master or Phi Phi Cruiser in advance for current policies. For fatigue management, utilize the rest areas at Khao Lak’s Mai Khao Beach viewpoint or the PTT petrol stations just south of Phang Nga town. Hidden off-route gems include the Talay Mok (Morakot Cave) in Krabi, accessible only at low tide, and the hot springs at Khlong Thom, a short detour from the main route.

The main route follows Highway 4 (Phet Kasem Road) south from Takua Pa, then merges onto Highway 402 toward Sarasin Bridge and Highway 4018 to Krabi. From Krabi Town, you’ll head to the Nopparat Thara Pier or Ao Nang, but note that ferries to Phi Phi also depart from Phuket (Rassada Pier) and Krabi’s Klong Jilad Pier. The drive is straightforward, but you'll need to factor in a short ferry ride to complete the journey.

• Distance from Takua Pa to Krabi Town: ~180 km (112 miles).
• Sarasin Bridge connects Phang Nga to Phuket; it’s the only road link between the mainland and Phuket.
• Fuel costs: Expect to pay roughly 1,200 Baht for a round trip in a small car (assuming 10 km/l and 35 Baht/litre).
• Tolls: Highway 4 has no tolls, but parking at the pier costs 50-100 Baht per day.

Khao Lak’s coastline, with its sandy beaches and palm-fringed coves, marks the start of your southward drive; the road hugs the coast for a stretch before turning inland through rubber and oil palm plantations. The Khao Sok National Park, a short detour off Route 4, is part of the Greater Phang Nga Forest Complex—a UNESCO World Heritage Site—with ancient rainforests and the Cheow Lan Lake reservoir. The park’s limestone karsts, some rising over 300 meters, are a highlight for nature enthusiasts.

Phang Nga Bay, dotted with over 150 limestone towers, is another must-visit; its famous James Bond Island (Ko Tapu) attracts many boat tours. Local commerce thrives along the route, with roadside stalls selling fresh pineapples, cashews, and Khao Lak’s signature seafood noodles. Don’t miss the chance to try the region’s signature dishes, such as Gaeng Som (sour curry) or Hokkien Mee, at local eateries in Phang Nga town.
